7210 SAS-X and 7210 SAS-R6 OS Quality of Service Guide
Applied at...
• Defines up to 32 forwarding class meters and meter parame-
ters for traffic classification. On 7210 SAS-X, support for
ingress queues is available.
• Defines match criteria to map flows to the meters based on
any one of the criteria (IP or MAC or both IP and MAC).
• Defines up to 8 forwarding class queues.
• Maps forwarding classes to the queues.
• Defines Queue parameters for the queues.
• Defines FC to remarking values.
• Defines CIR levels and PIR weights that determines how the
queue gets prioritized by the scheduler.
Packets are marked using QoS policies on edge devices.
Invoking a QoS policy on a network port allows the packets
that match the policy criteria to be remarked.
• Used for classification/marking of MPLS packets.
• Defines MPLS LSP-EXP to FC mapping and 12 meters used
by FCs, at ingress.
• Defines FC to MPLS LSP-EXP marking, at egress.
• Used for classification/marking of IP packets.
• At ingress, defines DSCP or Dot1p to FC mapping and 8
meters.
• At egress, defines FC to DSCP or Dot1p marking or both.
• Defines forwarding class mappings to network queues and
queue characteristics for the queues.
• Defines the CBS and MBS parameters for the queues.
• Enables or disables the high-slope and low-slope parameters
for the queues.
• Defines the forwarding class to remarking values.
